Performance adjustment method of axial flow pump

There are two methods to adjust the performance of axial flow pumps :

1. Variable speed adjustment We already know that the axial flow pump works at a certain speed and obtains the corresponding flow, head, power and efficiency. When the speed is changed, its performance parameters are changed accordingly, so as to achieve the purpose of adjustment. If the axial flow pump is powered by a diesel or gasoline engine, the throttle can be changed to change the speed. If the axial flow pump is connected to the power engine by a V-belt or a flat belt indirect transmission, you can change the diameter of the drive pulley to change the speed and replace Either the driving wheel or the driven wheel can be used for the purpose of changing the transmission speed ratio. Variable speed adjustment of pump performance is relatively economical and has a wide range of applications. It can be used for all agricultural water pumps.

2. Variable angle adjustment From the structural point of view, the axial flow pump impeller has a huge hub, which is convenient for installing adjustable angle blades. When the installation angle of the blades of the axial flow pump manufacturers changes, the lift force of the blades on the water changes, which changes the working performance of the water pump. This is the variable angle adjustment of the axial flow pump. With the increase and decrease of the blade installation angle, the flow, head and power of the axial flow pump will change accordingly. However, there is no change in the higher efficiency point, which is extremely beneficial to the performance adjustment of the axial flow pump.

The shape and working principle of the axial flow pump are different from the centrifugal pump, and its performance is also very different. In actual work, we must strictly distinguish them and use different methods to guide production practices and solve production problems. The performance of axial flow pumps is expressed by operating parameters. Flow, head, power, efficiency and other parameters have a certain relationship with each other. If the parameter relationship is expressed in the form of a curve, it is the pump performance curve. These curves are obtained experimentally by the pump factory and provide users with technical information. The change rules of flow and head, flow and power are the same. In general, the head and power gradually decrease with the increase of the pump flow, but there is a turn in the middle of the change process. As the flow increases, the head and power gradually increase, and then gradually decrease. When the flow rate is large, the efficiency is higher; when the flow rate Q = 0, the pump head and shaft power are about 1.5-2 times of the higher efficiency.
